Описание (английский):

ISO 1927-5:2012 specifies methods for the preparation and treatment (curing, drying and firing) of test pieces from monolithic (unshaped) refractory materials. The methods are applicable to dense and insulating castables and to ramming materials with the four types of chemical composition defined in ISO 1927-1:2012. The dimensions of the test pieces are specified and the preparation of the mixture, compaction methods, storage and post-treatment of the test pieces are described.

Overview

EN ISO 1927-5:2012 (CEN) - Monolithic (unshaped) refractory products - Part 5: Preparation and treatment of test pieces - specifies standardized methods for preparing and treating test specimens made from monolithic (unshaped) refractory materials. The document covers curing, drying and firing of test pieces for dense and insulating castables and ramming materials (four chemical types per ISO 1927-1). It defines specimen dimensions, mixture preparation, compaction methods, storage and post‑treatment to produce repeatable, comparable test specimens for laboratory evaluation.

Key Topics

Scope & applicability

Applies to dense/insulating castables, ramming mixes, taphole clays and dry vibration mixes.
Clarifies that laboratory specimen values are reference values and may differ from in‑service behaviour.

Dimensions and specimen shapes

Four standard shapes defined (A, B, C, D) with exact dimensions (e.g., Shape A: 230 × 114 × 64 mm). Shape C is the referee shape for inter‑laboratory testing; 50×50 mm cylindrical specimens permitted for some ramming mixes.

Mixture preparation and compaction

Procedures for mixing (pan mixer design and blade clearances), mixing speeds for dense and low‑intensity insulating castables, and riffle sampling.
Compaction methods include vibrating table (uniaxial, 50 Hz, specified amplitude), pneumatic rammer, sand‑rammer and hydraulic press (for plastics).

Curing, drying and firing

Defined post‑treatment sequences for castables, ramming mixes and plastics to achieve stable test pieces prior to property measurement.

Apparatus & reporting

Detailed apparatus requirements (mixer geometry and speeds, vibrating table amplitude, sand‑rammer design) and mandatory test report content (including green bulk density and vibration records).

Applications and Users

Who uses it

Refractory manufacturers, materials laboratories, R&D teams, QA/QC engineers, certification bodies and testing laboratories performing physical and mechanical tests on monolithic refractory products.

Practical uses

Producing reproducible test specimens for measuring physical properties (strength, density, dimensional change, etc.), inter‑laboratory comparisons, product development, quality control and conformity assessment.

Keywords: monolithic refractory, unshaped refractory, test piece preparation, castable test specimens, ramming materials, curing/drying/firing procedures, ISO 1927-5.
